One problem related to warning light on has been reported for the 2000 Chevrolet Blazer. The most recently reported issues are listed below.
I was notified by another driver I had no brake lights, brought back to dealer and informed that it would cost $400 to fix. Found out through my employer there had been a recall for this problem. Why was it not corrected before I purchased it from the chevy dealer. Also informed my airbag warning light was on and the a module was at fault and would cost another $550 to fix and that it may inflate airbag while driving. These are totally unrealistic problems to occur in a 2 year old model with less then 40,000 mi.
